Prompt causes javascripts to stop running

[Sausage]

Greasemonkey 0.9.13
Firefox 8.0
JQuery 1.7.0

I've written a user.js script for a webpage. The script uses the above pertinent information. The webpage already has scripts (i didn't write these) running which control timers, a running clock and a marquee. But the user script I've created, which prompts the user for a name, stops all scripts from running after the ok or cancel button is clicked. I've narrowed the entire script down to only a function call (with all other code removed from the script) where the function declares a variable and assigns the value of a prompt to that variable. That's when my user script stops running and also the original javascript running the timers, running clocks and marquee stop running as well.

getName();

function getName(){
var p;
p = prompt('Enter your name: ', '');

};

Other noteables...the original page includes JQuery 1.4.2.

This is #1318 and #1350 . It's Mozilla's bug.
